Speedy Printing charges $23 for 200 deluxe business cards and $35 for 500 deluxe business cards. Given that the cost is a linear function of the number of cards printed, find a formula for that function and find the cost of 700 business cards.

    It would help if you proofread your questions before you posted them.

    Since they are both "deluxe business cards," I would only get the ones at the lower rate.

    23/x = 200/700

    Solve for x.

    But that formula does not account for the 39% discount given on the 500 cards.
